Derbac M Liquid contains the active ingredient malathion, which helps kill parasites such as head lice, pubic lice, and scabies mites. It works by blocking the action of an enzyme in the parasite called cholinesterase, which is essential for the growth and survival of the parasite.
Some products for the treatment of head lice are flammable when on the hair, and can ignite and cause serious harm in the presence of an open flame or other source of ignition, such as when lighting cigarettes. The user of these products should keep away from people who are smoking, and open flames or other sources of ignition, including in the morning after an overnight application, until the hair is washed.
Please read the instructions that come with the treatment to ensure it is used safely and correctly.
Possible side effects of Derbac M Liquid:
